I've tried all the gentler recipes like Billy NoMates and garlic but I've given up. In a hill-farming area like this, the ticks are everywhere. So I'm using Advantix which is supposed to stop them latching on. I don't like it much but I don't want to risk Lymes Disease and there are enough deer to make it a distinct possibility. Advantix is not cheap either and it's a real pain trying to keep them out of the water for two days after it's been applied. But I haven't seen a live tick on either of them since I started although I have seen a few tiny, dead ones drop out of their fur. Grrrrrr - I can't understand why five critturs were ever created: midges, horseflies, mosquitos, slugs and blimin' TICKS.
